Many wood and vinyl fences use posts every 6-8 feet, depending on height and material.

How many concrete bags per post?

One to two 50-60 lb bags per post is common for residential fences, depending on hole size and depth.

Tips & notes

Assumptions that most often change the final quantity in the field—so you order with clearer eyes.

Mark corners and gate locations before calculating post spacing.

Shorten sections slightly rather than exceeding the maximum post spacing.

Use pressure-treated or rated posts for ground contact.

Call utility locating before digging post holes.
